Abstract: Catalysts containing phosphorus, vanadium and molybdenum have been found to be especially effective for the oxidation of methacrolein with molecular oxygen to obtain methacrylic acid. The catalysts may be optionally promoted with Bi, As, B, Ce, Cr, Ag, Fe, W, Pb, Mn, Tl, Te, Ni, Nb, B, Sn and/or Cu.

Abstract: Catalysts containing the oxides of molybdenum and phosphorus promoted with rubidium and at least one element selected from the group consisting of As, Cd, In, Sn, Tl, K, Ca, V, U, Ce, W, Ni, Zr, Ba, Fe, Rh, Mn, Re, Ru, Co, and Cu have been found to be especially desirable in the vapor phase oxidation of acrolein and methacrolein with molecular oxygen to yield acrylic acid and methacrylic acid respectively. The reaction of methacrolein gives an especially pure product in high yields and selectivities of methacrylic acid.

Abstract: PROCESS FOR THE PREPARATION OF UNSATURATED ACIDS FROM UNSATURATED ALDEHYDES Methacrylic acid or acrylic acid are produced by the oxidation of methacrolein or acrolein respectively, with molecular oxygen in the vapor phase in the presence of a catalytic oxide of molybdenum, phosphorus, and promoted with chromium or at least one element selected from the group consisting of thallium, rubidium, cesium, potassium, titanium and arsenic, or a mixture thereof, wherein at least part of the molybdenum employed in the preparation of the catalyst is supplied in the form of molybdenum trioxide. The oxidation of methacrolein in the presence of a catalyst wherein all the molybdenum employed in the preparation of the catalyst has been supplied by molybdenum trioxide gives especially desirable high yields and selectivities to methacrylic acid.
